SECTIONAL BAND FOR SPRINGS.

SPECIFCATION forming part 0f Letters Patent N0. 537,997, dated April.23, 189 5.

Application filed November 9,1894. Serial No. 528,292- (No model.) .Y

To all whom it may concern.-

Be it known that I, GEORGE BEALE SLoAN, Jr.. of Oswego, in the county ofOswego, in the State of New York, have invented new and usefulImprovements in Sectional Bands for Springs, of which the following,taken in connection with the accompanying drawings, is a full, clear,and exact description.

My invention relates to bands forV leafsprings such as full orsemi-elliptic springs, and the object is to provide ya band which may bequickly and readily applied to or removed from a spring when the latterbecomes broken.

When a leaf in a spring becomes broken, the broken leaf can be removedand a newone inserted easily and quickly without injury to the band. l

To this end my invention consists `in the combination of a band for leafsprings divided into sections, and suitable means whereby the sectionsmay be locked together, and my invention consists in certain othercombinations of parts hereinafter described and specifically set forthin the claims.

In the drawings hereto annexed and forming a part of this specification,Figure l is a side elevation of a semi-elliptic leaf springprovided witha band embodying my inven# tion. Fig. 2 is a side view of the same bandenlarged, removed from the spring, and taken on line or, 0;, of Fig. l.Fig. 3 isa top plan view of the band. Fig. 4 is a top plan view with thetop plate or locking device removed. Fig. 5 is a viewpof the inner sideof one of the parts of the band. Fig. 6 is a top plan view of the plateor locking device removed from the band. Fig. 7 is a sectional view ofthe plate taken on line y, 'tz/,of Fig. 6. Fig. S is a side elevation ofa modified form of a divided or sectional band. Fig. 9 is another sideview of the same. Fig. 10 is the inner side view of the parts of theband; and Fig. ll is one of the rings or locking devices for holding theparts together.

Referring specifically to the drawings, A indicates a spring which, asshown in Fig. 1, is built up of leaves of different lengths and istermed a semi elliptic spring. I do not, however, limit myself to theyapplication of my invention to semi elliptic springs for it will beobvious that if the invention can be part.

applied to these it can also be applied to all other leaf springs, asfull, quarter elliptic springs, or straight springs.

B indicates the band for holding theleaves together. This band isdivided into two parts as shown clearly in the drawings, each part beingthe same in size and shape as the other The band is divided centrallyand preferably on a vertical plane as shown in Figs. l to 5 inclusive,but it may be divided in other suitable Ways as for instance in the wayshown in Figs. 8, 9 and lO. In these figures the band is shown dividedon a horizontal plane so that the locking devices are on the sides ofthe band instead of on the bottom and top thereof.

Referring to the first seven figures of the drawings, it will be seenthat each part of the bandhas on both its top and bottom sides a semicircular projection, b, b, which projections, when the parts of the bandare placed together properly, will form two circular projections. Eachof these circular projections is provided with small lips or extensionsb', b', on diametrically opposite sides. These projections together withthe lips engage the locking plate, the lips serving to hold the plate tothe band.

O, O are the locking devices or plates which are designed to hold theparts of the band together. Each locking device or plate is provided inits center with a hole just large enough to admit the projections, b, b,and this plate has recesses, e, c, on diametrically opposite sides ofthe hole but in a linelying at an angle to a side edge of the plate, topass over the said lips, b', b.

When a plate or locking device, C, is placed in position to inclose thecircular projections on the band, the lips pass through the recesses andthe plate drops down to the side ofthe band. Then the plate, C, isrotated' on the projection until it lies square with the side of theband. The said plate may be held against rotation or displacement by anysuitable means, as by a small pin, d, passed through the plate and bandas shown in the drawings. In order to allow for the rotation of theplates, C, O, when the plates are equal in thickness to the length ofthe projections on the band, I countersink the holes in the plates asshown; If the plates were thin this IOO would not of course benecessary. lIn order that the parts of the band will registeraccurately, I provide each part with a small pro jection, e, whichenters a cavity in the opposite part as will be understood.

The locking devices, C', C', shown in Figs.

.8, 9 and 11 are in the form of rings with recesses in their outer edgeson diametrically opposite sides. The rings are made of thin steel andinclose circular projections, b, b, on the sides of the band,but thelocking devices having a ring form are provided with circular cavitiesor grooves, f, f, surrounding the projections to lie in. The lips, b',b', are in this case not on the projections, Z9, b, but are formed onthe outer walls of the circular grooves,f,f. After the rings areinserted in the grooves they are rotated more or less to pjarytherecesses therein away from the lips,

I do not wish to be limited to constructions herein shown and describedas it will be obvious that these constructions may be varied in manyways without departing from my invention.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

l. A rectangular band for leaf spings divided centrally into two parts,a locking device on each of two sides of the band, and means on saidsides to engage the locking de vices, substantially as and for thepurpose set forth.

2. A band for leaf springs divided into two parts equal in size andcorresponding in shape to each other, and a pair of locking devices forholding said parts together and releasing said parts when desired, asand for the purpose described.

3. A band forleaf springs divided centrally and vertically in two parts,a locking device on the top and bottom sides of the band, and means onsaid sides of the band to engage the locking devices, as set forth.

4. A rectangular band for leaf springs divided centrally in two parts,semi circular proj ections on each part lying opposite each other andplates provided with apertures to inclose said projections, as setforth.

5. A rectangular band for leaf springs divided centrally in two parts,semi circular projections on each part lying opposite each other andprovided with lips, and plates provided with apertures to inclose saidprojections and recesses in the sides of `the apertures, as and for thepurpose described.

6. A band for leaf springsdivided centrally into two parts, a locking.device on each of the divided ends to hold the parts together, andsuitable means to secure the locking devices against displacement, asset forth.

In testimony whereof I have hereunto signed my name.
